1. Amish Barn. Just ate there on a recommendation and had 4 for 4 bad meals. Turkey was tough and tasteless, pork/sauerkraut was inedible, kids didn't eat their food (OK, one of them is picky, but the other usually likes everything). To their credit, they didn't make us pay for the sauerkraut, but I made a solemn vow to my family never to go there again.
2. King Buffet. They have perinnially low health inspector ratings. The last time we ate there 3 of the 4 of us became violently ill within hours.
3. Willow Valley. Some of their food is still OK, but the quality has steadily degraded over the years. They are a shadow of their former self.
